More Men Die from COPD Compared to Women

(PhysOrg.com) -- Men across the Asia-Pacific region have consistently higher mortality and hospitalization rates for chronic obstructive pulmonary disease (COPD) than corresponding rates for women in the region.

Intel and Adobe to Extend Flash Platform to TVs

Adobe Systems and Intel today announced plans to collaborate on the development to port and optimize Adobe Flash technology for the Intel Media Processor CE 3100. This effort is expected to provide consumers with richer and more seamless Web-based and video viewing experiences through advanced Intel-based cable set-top boxes, Blu-ray Disc players, digital TVs and retail connected AV devices.

New hope for cancer comes straight from the heart

Digitalis-based drugs like digoxin have been used for centuries to treat patients with irregular heart rhythms and heart failure and are still in use today. In the Dec. 16 issue of the Proceedings of the National Academy of Sciences, researchers at the Johns Hopkins University School of Medicine now report that this same class of drugs may hold new promise as a treatment for cancer. This finding...

Prolonged nevirapine in breast-fed babies prevents HIV infection but leads to drug-resistant HIV

Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report. But the investigators highlight the proven superiority of the six-week regimen in preventing mother-to-child HIV transmission in...

Physicists offer foundation for uprooting a hallowed principle of physics

Physicists at Indiana University have developed a promising new way to identify a possible abnormality in a fundamental building block of Einstein's theory of relativity known as "Lorentz invariance." If confirmed, the abnormality would disprove the basic tenet that the laws of physics remain the same for any two objects traveling at a constant speed or rotated relative to one another.

Effect of subliminal marketing greater than thought

(PhysOrg.com) -- Marketing statements influence us subliminally more than was ever assumed. Even when you are not aware of being exposed to advertising material, it can still affect your actions. This emerged from research by Marieke Fransen of the University of Twente, Netherlands, who obtained her doctorate from the Faculty of Behavioural Sciences on 19 December.

Teaching intangibles with technology

Teach students some facts, and they learn for one exam at a time. Teach students to think and they learn how to learn for the rest of their lives. Ambitious work from European and Israeli researchers is making it easier to help students learn to think for themselves. This is exciting stuff for teachers.

Brown Dwarfs Don't Hang Out With Stars

(PhysOrg.com) -- Brown dwarfs, objects that are less massive than stars but larger than planets, just got more elusive, based on a study of 233 nearby multiple-star systems by NASA's Hubble Space Telescope. Hubble found only two brown dwarfs as companions to normal stars. This means the so-called "brown dwarf desert" (the absence of brown dwarfs around solar-type stars) extends to the smallest...

Collagen VI may help protect the brain against Alzheimer's disease

Scientists from the Gladstone Institute of Neurological Disease (GIND), UCSF, and Stanford have discovered that a certain type of collagen, collagen VI, protects brain cells against amyloid-beta (Aβ) proteins, which are widely thought to cause Alzheimer's disease (AD). While the functions of collagens in cartilage and muscle are well established, before this study it was unknown that collagen...

Researchers create all seeing 'eye'

The remarkable ability of insects to look in all directions at once has been emulated by a team of international scientists who have built an artificial 'eye' with an unobstructed all-round view.

'Recovery coaches' effective in reducing number of babies exposed to drugs

About 11 percent of the 4 million babies born in the U.S. each year have been exposed to alcohol or illicit drugs in the womb, according to a June 2006 report by the National Center on Substance Abuse and Child Welfare. If removed from the home by child protection, these children tend to remain in foster care longer, and chances are very low that they will be reunited with their parents.
